DYElNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 528,584, dated November6, 1894.

Application filed January 31,18 94. Serial No. 498,551- (No model.)

Z'o aZZ whom t may concern,.-

Be it known 'that I, MURRAY BACON, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia, in the State ofPennsylvania, have invented a certain new and useful Improvement inDyeing- Machines, of which the following is a true and exactdescription, reference being had to the accompanying drawings, whichform a part thereof.

My invention relates to dyeing machines, and particularly to mechanismfor'raisin g the yarns out of the dye liquor, and has for its mainobject to provide mechanism whereby the yarns may not only be raisedfrom the tank, but carried to one side thereof so that they can beconveniently removed.

My invention is best described in connection with the accompanyingdrawings, in which- Figure 1 is a side elevation of a dye tank providedwith myimprovements. Fig. 2 is an end elevation of a tank, showing thepreferred means for operating mechanism both for moving the yarncarrying bars and for lifting them from the tank. Fig-3 is a side Viewon a smaller scale with some of the parts removed showing the yarnlifting mechanism in another position. Fig. 4 is a plan view showing oneform of yarn bar carrying frame, and Fig. 5 a similar View showinganother. form of frame, the frames shown in Figs. 4 and 5 being on thescale adopted in Fig. 3.

A is a tank of any suitable size or shape and adapted to hold dyeliquor. The yarns as r are adapted to be supported in the tank by meansof yarn carrying bars r which are preferably moved along the edge of thetank by suitable mechanism so as to insure that the yarns will bethoroughly impregnated with the dye liquor. Themechanism I employ forthis purpose is preferably that shown in the application of George H.Craven, Serial N o. 459,388, iled January 25,1893, and which consists ofa rack K operated by suitable cranks K3 and which takes all the bars insuccession and moves them forward a certain distance at each revolutionof the cranks; arms F having sockets F being adapted to take single barsas they are brought to one end of the tank by the rack K and carry themback to the other end. In the construction shown in that application aframe as K normally rests on the edge of the tank during the dyeingoperation and is adapted to support the yarn carrying bars when they arenot being moved by the rack K. In my pres- 'ent invention I providemeans for raising Fig. 4. Connected to this frame are means for raisingit from the tank and lifting it to one side thereof, so that, as shownin Fig. 3, the yarn maybe inspected or deposited upon a truck, as M, andremoved. These'means may be any which are found convenient, but I preferto arrange suitable arms on the frameof themachine so that thesamesource of power, which drives the other mechanism of the tank, may beused to operate the arms for raising the frame. As shown in Figs. 1, 3and 4, arms J J pivoted on the frame A of the machine at j j aresecuredor pivoted to the frame K at Z l respectively, so that when the arms arerotated, as indicated by the dotted direction lines in Figs. 1 and 3,the frame will be raised from the tank and carried toene side as shown.In this construction, however, the yarn carrying bars only would bedeposited on the truck and the frame would be returned to the tank bythe backward movement of the arms J J. In Fig. 5, however, the arms J Jare shown pivoted to anauxiliary frame L L on which the frame K rests,so that the frame K may be entirely removed, if desired, With itscomplement of yarn bars. vious, that while it is preferable to employthe rack frame Kto raise the yarn bars, it is not necessary, since, asshown in dotted lines in Fig. 3, the arms JJ may be pivoted to anindependent frame L which engages with and lifts the bars. The frame Ktherefore may simply consist of two racks fastened one on each side topedge of the tank.

.The preferred form of mechanism for operating the 4tank is best shownin Figs. 1 and 2. B B B2 are pulleys, the pulley B being It is also, ofcourse, obl IOO loose. The pulley B2 through bevel gear b2 c transmitsmotion to a worm C on the shaft c. This worm C drives a gear D on shaftd and by means of bevel gears Z2 e drives the shafts e', one on eachside of the tank. The shafts e drive the arms Fand the cranks K3 whichserve to move the yarn carrying bars along the tank. The pulleyB throughgears b and g drives worm G on shaft g. This drives gear H on shaft 7L.On the wheel I'I is a crank pin 71, and on a crank I-I at the other endof the shaft h a corresponding pin h as shown in Fig. 2. Pivoted onthese pins are arms I which are pivoted to arms J at J and serve torotate them, as shown, on the turning of the shaft h.

It will of course be understood that any preferred sort of gearing maybe employed, and the gearing shown is simply a very convenient form foreecting the operation desired. The lifting mechanism can of course bedriven by an entirely independent motor, as the pulley B3, from thatwhich drives the other mechanisms, but'by adopting the constructionshown, an important advantage is gained since, one belt being used todrive the pulleys B B2, it will be impossible for the lifting mechanismto be put in operation while the racks, or other devices, are engaged inshifting the bars along the edge of the tank. A suitable belt-shifterfn. is employed to shift the belt from one pulley to another.

Another advantage is that the worm gear G serves as a lock to preventany movement of the gear wheel H when the worm is not driving it. Thisenables the operator to raise the yarns out of the dye liquor to drain,or to renew or stuft the liquor, the arms J J being held securely in anyposition by the lookin g action of the worm gear.

It will be noticed that the distance h-h is less than j-I, that is, thehalf throw of the crank pin 71. is less than the distance from thepivotal point of the arms J to the point where the connecting rod or barI is pivoted to it, so that a continuous rotary motion of the gear Htransmits an oscillating motion to the arms J J.

In operation, when it is desired to lift and remove the yarns thedriving belt is shifted to the pulley B, or if an independent motor isemployed to drive the lifting mechanism this is put in operation, andthe arms J J are operated till they are in the position shown in Fig. 3when the load of yarns can be readily removed and carried off, as bymeans of the truck M. Another truck can be pushed into place and a newlot of yarns put in position. The motor for operating the arms is againput in operation and the yarns are lifted into the tank by a continuousmotion of the motor.

If through inadvertence the shaft h is permitted to continue rotating,the only effect the point j, as indicated in dotted lines, also a bar I2may connect the two arms J J which, being parallel, will always keep theframe K parallel to the position it has on the tank.

`It Will be noticed that the arms J J are preferably pivoted, not to thetank, but on an independent frame A which enables me to renew the tankor tub withoutinterfering with the means for operating the yarns.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a dyeing machine the combination with a tank of a frame adapted torest on the tank during the dyeing operation and support yarn carryingbars, arms suitably pivoted on the frame of the machine and to the yarnbar supporting frame and means for moving the arms so as to lift theframe from the tank and carry it to one side thereof.

7. In a dyeing machine the combination with a tank, means for movingyarn bars along IIO the edge of the tank, aframe, on which said bars areadapted to rest arms J J secured to the frame, and means for operatingthe arms J J so as to raise the frame and the yarn carrying bars fromthe edge of the tank.

8.
